Numerical Stability

Name: Anonymous 2007-11-13 22:18

This issue came up at work today, I thought ya /prog/ peeps might have some info.

So what do ya'll know about the numerical stability of rotations with, matrices, euler angles, and quaterions.

Also what do you know about the methods for interpolating rotations, and which method maintains numerical stability across the interpolation operation.

Haha, stupid fag got pissed off.

#1. IQ is not a valid measure of intelligence. Enjoy your mensa medals while real intelligent people make the discoveries.

#2. WRONG, they both have some common points but they do differ, for one, comp.sci also includes study of computation limitation and real world limitation as applied in machines.

#3. It is trivial. Point me to a algorithm which returns an answer that involves actual floating point calculation and I can make it spew out the incorrect answer.

People study numerical methods because of floating point inprecision? You fucking kidding me. Obviously bad Fraction class implementation is obviously bad.

List all million way to invert the matrix, if you want to keep asking stupid questions and give half-assed rebuttal without valid proof then I would too.

You obviously don't understand real world implementations, ever wonder why x87 and other high precision floats (GO AWAY C# and your faggotry decimal type) is listed as 64 bit but uses a 80 bit register? You're fucking retarded, anything involving floats will be inaccurate unless the number exist in a subset of the binary system 1/2^n.

Smart troll, neithertheless has the intelligence of a dead fish.

"Ya'll" is not the right way to use punctuation, "Y'all" is the accepted form. Take some english before coming here after reading some wiki and thinking you're the next Einstein. And enjoy your checkout job.
